I am able to connect using my Iphone, and of course the Outlook Web app through chrome browser works fine (been using that for weeks) but Outlook/Thunderbird keep giving username/password prompts and/or no connection whatsoever.
I've exhausted all profile recreation in control panel for Outlook 2007 AND 2010, flush dns, etc etc and manual & auto port/encryption settings in Thunderbird (gone through all the combinations) but keep getting a "either user name or password is incorrect" nonsense.
The same credentials work absolutely 100% fine for my phone and browser email access.
Outlook: "Cannot connect to exchange" no matter what I do
Additional Info: GMAIL, YAHOO email accounts work PERFECTLY with Outlook- no issues connecting and downloading thousands upon thousands of messages. But the Comcast Business Email Account... was dead as a doorknob. No connection whatsoever.
I installed Outlook 2010 on my home pc too and tried connecting to my work email- cannot connect to exchange server.
However, using my Gmail account to test I get 100% success. Is there a block on my email account preventing an email client from connecting to it?
Comcast Tier 2 Technicians resolved the issues. Problems were with the Comcast Exchange mail server and the associated email accounts of my workplace domain- some accounts had configuration bugs on the Exchange Mail Server side and were resolved, a few still had login/autodiscover settings problems when trying to connect an email client program to the mail account. Exchange mail server would not accept log in requests from Outlook.
As of 2/19/16 it seems all email accounts in Outlook are able to Connect to Mail server and get appropriate settings and Log On (and staying logged on).
Anyone reading this- please contact comcast if you have email issues and reference this topic, it will save you a lot of time trying to find a problem with Outlook when there was never any to begin with.
